Ok it was late and those two were all I could think of. So, I think Rogue is right, the first to do a custom W/C was r11, then Photonmoo joined but didn't add W/C until I came along, then I joined and mine was built with W/C, his was added on later, then you added yours some time in Jan.
I do think Kev_b was the first to have an H50.
I'm not sure, if it really matters to you either General Enigma can settle this or I can check it out over the next week or so.
Here's a funny post from the past from Enigma:
@ Enigma, Please change the sentence over my picture on the first page, it says that the video card is a 5970, it is in fact a 5870, they didn't even have 5970's when I bought my card. Thanks!
It's so funny to look at the old posts, there were so many guesses as to what the new Nvidia cards would be called, GF100's, GX300's, then it turned out to be GT- 400's,
Looking at old pics can be fun indeed, looked back in the thread until where I joined and my PC wasn't very pretty then, nor was my cellphone pics xD
